The network connection profile corresponding to the international mobile subscriber identity code is set and set as the network connection profile used by the SIM card, so that the user can conveniently use the network service without having to know the network knowledge. There is no need to manually switch and set up a new network connection.

Referring to FIG. 1, an application environment diagram of a preferred embodiment of a system for switching a handheld device network connection according to the present invention is shown. The system 14 for switching the handheld device network connection (hereinafter referred to as the system 14) operates in a handheld device 1, such as a mobile phone and a PDA. The system 14 is configured to automatically connect a network connection corresponding to the Mobile Country Code (MCC MNC) of the SIM card 10 when the user switches to use a different SIM (Subscriber Identity Monule) card 10. Profiles allow users to easily access network services without having to know about network settings and simplify network connection setup. The MCC is a mobile country number consisting of 3 digits, which uniquely identifies the country to which the mobile subscriber belongs. For example, China's mobile country number is 460. The MNC is a mobile network number consisting of 2 digits and is used to identify the mobile network to which the mobile subscriber belongs. Mobile networks such as GSM (Global System for Mobile communication) and CDMA (Code Division Multiple Access).

The data stored in the SIM card 10 can be classified into four categories: The first type is data that is pre-fixed and stored. Such data is written by the SIM card center before the mobile phone is sold, including MCC MNC, authentication keys, authentication and encryption algorithms. The MCC MNC pre-stored in the SIM card 10 cannot be modified or deleted by the user; the second type is temporarily stored information about the network, such as a location area identifier, a mobile subscriber temporary identifier, and a public telephone network code that is prohibited from accessing. The third category is related business codes, such as personal identification number, unlock code, billing rate, etc. The fourth category is the telephone directory. Almost all of the user's data is stored in the SIM card, so the SIM card is also called the "user data identification card." In actual use, there are two kinds of SIM cards with the same functions and different forms: card type (commonly known as big card) SIM card. This type of SIM card conforms to the ISO7816 standard for IC cards, similar to IC card; embedded (commonly known as small card) The SIM card, which is only 25 mm x 15 mm in size, is a card that is semi-permanently loaded into the mobile station device.

In the preferred embodiment, the SIM card 10 is an embedded SIM card.

The handheld device 1 further includes a database 12. In the preferred embodiment, the database 12 can be a FLASH flash memory for storing at least one set of MCC MNC codes and corresponding network connection settings. files. This network connection profile can be used for all network services such as WAP, MMS, JAVA, etc. Typically, the handheld device 1 defaults to one of the MCC MNC codes as the first set of MCC MNC codes.

Referring to FIG. 2, it is a functional unit diagram of a system for switching a network connection of a handheld device according to the present invention. The system 14 includes a reading module 100, a matching module 110 and a setting module 120.

The reading module 100 is configured to read the MCC MNC code pre-stored in the SIM card 10, and is also used to read the MCC MNC code stored in the database 12.

The comparison module 110 is used to compare the MCC MNC code pre-stored in the SIM card 10 with the MCC MNC code in the database 12.

The setting module 120 is configured to read the corresponding network connection profile according to the comparison result of the comparison module 110 to switch the network connection used by the current SIM card. Specifically, when the MCC MNC code pre-stored in the SIM card 10 is the same as the MCC MNC code in the database 12, the network connection profile corresponding to the group MCC MNC is read, and the network is read. The road connection profile is set to the network connection profile used by the SIM card 10 to switch the network connection used by the current SIM card 10. When the MCC MNC code pre-stored in the SIM card 10 is different from the MCC MNC code in the database 12, the network connection profile corresponding to the default first MCC MNC code in the database 12 is read, and The network connection profile is set to the network connection profile used by the current SIM card 10.

3 is a flow chart showing the operation of the method for switching a network connection of a handheld device according to the present invention. In step S300, the user inserts the SIM card 10 in which the MCC MNC code is stored in advance into the handheld device 1 and turns it on.

In step S301, the reading module 100 reads the MCC MNC code pre-stored in the current SIM card 10. The MCC MNC pre-stored in the current SIM card 10 cannot be modified or deleted by the user.

In step S302, the reading module 100 reads at least one set of MCC MNC codes stored in the database 12. Each group of MCC MNC codes corresponds to a network connection profile, which can be used for all network services, such as WAP, MMS, JAVA, etc.

In step S303, the comparison module 110 compares the MCC MNC code pre-stored in the current SIM card 10 with each set of MCC MNC codes in the database 12.

In step S304, the setting module 120 reads the corresponding network connection profile according to the comparison result of the comparison module 110 to switch the network connection used by the current SIM card 10. Specifically, when the comparison module 110 compares the MCC MNC code in the database 12 that is identical to the MCC MNC code pre-stored in the SIM card 10, the network connection profile corresponding to the MCC MNC code is connected. And set it to the network connection profile used by the current SIM card 10 to switch the network connection used by the current SIM card 10. When the comparison module 110 does not compare the same MCC MNC code as the SIM card 10 in the database 12, the network connection profile corresponding to the default first MCC MNC code in the database 12 is read. And set it to the network connection profile used by the current SIM card 10.
